The jihadi cells in the aforementioned places are already under watch, and many have already been arrested. I am confident in the ability of DHS to continue that work. I am not confident though in the loyalty of the jihadi neighbors and family members of those same jihadis as they have done nothing to demonstrate that it's their.
Then why do you disagree with their choice to ignore the Nuke Mecca Crowd's braying about the need to arrest all Muslims everywhere, regardless of their actions, intentions, or affiliations?
